Sorting method of frequency hopping communication radio stations

The invention relates to a sorting method of frequency hopping communication radio stations. The sorting method comprises the following steps: step 1, initializing and setting an optimal feature subset; step 2, acquiring a feature set S = (s1, s2-sM) of the frequency hopping communication radio stations; category information D of the frequency hopping communication radio stations; step 3, selecting I (si; d) the maximum value is a candidate feature si; step 4, repeatedly executing the step 2 and the step 3 to form a candidate feature subset sk; step 5, indicating that Sp belongs to Sselect; calculating VJMI = I (sk, sp; d) enabling V to be equal to VUVJMI, and taking the minimum value of V as UJMI as the minimum joint mutual information; step 6, in all candidate features si of the candidate feature subset sk, selecting a feature enabling the value of the minimum joint mutual information to be maximum; setting U to be equal to UU, UJMI, and f to be equal to max (U); wherein S < select >is equal to S < select >
